Linear Regression Model

Model equation:
Yi = α + β × Xi + εi

Top border of price channel:
Exp(Yi) = Exp(a + b × Xi + 2 × s)

Bottom border of price channel:
Exp(Yi) = Exp(a + b × Xi – 2 × s)

where:

i - observation number
Yi - natural logarithm of VST price
Xi - time index, 1 day interval
σ - standard deviation of εi
a - estimator of α
b - estimator of β
s - estimator of σ
Exp() - calculates the exponent of e


Primary Trend

Start date: March 24, 2023
End date: November 20, 2024

a = -0.9297

b = 0.0032

s = 0.1402

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0032) – 1
= 217.05%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.1402) – 1
= 75.21%

March 24, 2023 calculations

Top border of price channel:

Exp(Y839)
= Exp(a + b × X839 + 2 × s)
= Exp(a + b × 1,219 + 2 × s)
= Exp(-0.9297 + 0.0032 × 1,219 + 2 × 0.1402)
= Exp(3.2044)
= $24.64

Bottom border of price channel:

Exp(Y839)
= Exp(a + b × X839 – 2 × s)
= Exp(a + b × 1,219 – 2 × s)
= Exp(-0.9297 + 0.0032 × 1,219 – 2 × 0.1402)
= Exp(2.6436)
= $14.06

= Exp(a + b × X1,257 + 2 × s)
= Exp(a + b × 1,826 + 2 × s)
= Exp(-0.9297 + 0.0032 × 1,826 + 2 × 0.1402)
= Exp(5.1234)
= $167.90

Bottom border of price channel:

Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)

= Exp(4.5626)
= $95.83
